Taco 0012-SF4-2 Stainless Steel Pump 1-1/2″ Flanged

With a 1-1/2-inch flanged standard port, the Taco 0012-SF4-2 is a stainless-steel circulator with a 1/8 HP motor. Published maximum values are 45 GPM and 13 feet of head. The stated application is commercial hot-water recirculation, where flange compatibility, actual loop resistance, and required circulation should be reviewed before equipment selection.

Stainless-steel construction identifies the supplied body material, while maximum hydraulic values establish performance limits rather than a fixed operating point. Final selection should use the applicable Taco curve and account for pipe length, fittings, water temperature, pressure, and connected equipment. Confirm that the 1-1/2-inch flanged interface matches the installed recirculation piping before replacement or new installation.

Key Specifications of the Taco 0012-SF4-2 Stainless Steel Circulator

- A 1-1/2-inch flanged standard port provides the listed connection size for matching commercial recirculation-loop piping.
- Stainless-steel construction identifies the specified body material for this flanged Taco circulator pump configuration.
- The 1/8 HP motor establishes the listed drive size for the supplied commercial hot-water recirculation unit.
- Published maximum flow reaches 45 GPM, defining the stated upper circulation limit rather than a fixed operating result.
- Maximum head is listed at 13 feet, requiring comparison against actual recirculation-loop resistance before equipment selection.
- Commercial hot-water recirculation is the stated application context for evaluating this stainless-steel circulator configuration.

Hydraulic Performance and Application

The Taco 0012-SF4-2 is specified for commercial hot-water recirculation with 45 GPM maximum flow and 13 feet maximum head. These figures define published performance boundaries, not a guaranteed condition for every loop. Select using the relevant Taco curve and project system resistance. Pipe length, fittings, water temperature, pressure conditions, and 1-1/2-inch flanges determine the actual operating point.

Installation and System Requirements

Verify a compatible 1-1/2-inch flanged piping arrangement before ordering this circulator. Compare required loop flow and total head with the applicable Taco performance curve, then review water temperature, system pressure, electrical supply, and installation space. Support adjacent piping so it does not load the pump body. Follow official documentation for mounting, wiring, startup, and service of this exact configuration.

Why Choose the Taco 0012-SF4-2

This model combines a stainless-steel body, 1-1/2-inch flanged port, and 1/8 HP motor for commercial hot-water recirculation. Its 45 GPM maximum flow and 13-foot maximum head create initial selection boundaries. Buyers should compare those values with the actual loop curve, existing piping connection, water conditions, and required circulation rate before specifying the final pump arrangement.

Warranty and Support

Taco 00 Series circulators carry a 3-Year Limited Warranty from the manufacturer date code. Taco states that products proven defective under normal use may be repaired or replaced under its warranty terms. Coverage remains subject to current conditions and exclusions. Mulmotor provides pre-purchase product guidance and order-related customer support before your purchase is placed.

Before Ordering the Taco 0012-SF4-2 Stainless Steel Circulator

Before ordering, confirm that your commercial hot-water recirculation loop uses a 1-1/2-inch flanged connection. You should compare required flow and head loss with the published 45 GPM and 13-foot maximum limits using the relevant Taco curve. Review water temperature, system pressure, electrical requirements, mounting space, and pipe-support needs. Confirm that the stainless-steel body matches documented project requirements.
